T0 aZZ wwm it may concern:

Be it known that I, FRANK L. Wnsrcn0on, a citizen of the United States,residing .at Fish, in the county-of Folk and State of Georgia, haveinvented certain neW and useful Improvements in Plows, of Which thefollowing is a specification.

This invention relates to turning plows and seeks primarily to proviclea point Which may be readily adjusted to compensate for wear and whichmay be used for a long time efficiently. The invention also seeks toprovide a point which is reversible so that it may be used in the fieldwithout any appreciable 1oss of time. The invention also seeks toprovide novel means for adjusting the landside and the frog relative tothe point 50 as to obtain the desired penctration of the point, and alsoto provide an improved share.

The invention is illustrated in the accompanying drawingsand consists incertain novel features which Will be first fully described and then moreparticularlypointed out in the claims following the description.

In the drawings: 7

The beam 1 and the handles 2may be of any desired formation, the handlesbeing connected with the beam by braces 3 as shown and as is nowordinarily donc. The rear endof the-beam is turned downwardly to form astandard 4 and is secured to the frog 5 by a bolt- 6 inserted throughthe detail perspective view of the a detail perspective view of thestandard and a longitudinal slot 7 in the,

frog near the upper rear corner of thesame, the lower end of thestandardbeing secured to-the frog by abolt 8 which firmly secures theparts together but may operate as a pivot to permit relative adjustmentof the stand- The landside 9 is pivotally attached at its front end, as

shown at 10, to the side of the frog near the lower edge thereof and thefrog W111 pref 'erably be constructed with a concave scat to receive thefront end of the landside, as shown in Fig. 2. The landside is providedwith a heel or flange 11 at its lower edge which projects under thelower edge of the frog and is Wider at its rear end than at its frontend. This construction gives the lands1de a firm bearing upon the groundin the bottom of the furrow and also permits the 'landsideto be soadjusted that it Will run on the bottom of the furrow notwithstandingthe angle to Which the point may be adjusted. Near its rear end thelandside carries a bolt 12 which passes through a vertical slot 13 inthe frog so that the vertical adjustment of the rear end of the landsidemay be accommodated and the landside secured firmly in any position inWhich it may be set. To further aid in holding the landside in itsadjusted position, lugs or corrugations 14 are provided on the opposedadjacent faces of the landside and of the frog so that when the bolt 12is tightened the corrugations or lugs are firmly engaged and preventrelative vertical movement of the frog and landside. The boit 12 alsoserves .to 'secure the lower ends of the handles to the frog.

The front edge or corner of the frog is formed on a regular curve Whichmay be of any desired radius according to the size and weight of theplow. The point 15 consists of a bar of tempered steel which is bentfrom end to end on a curve corresponding exactly with the 7curvature ofthe front edge of the frog so that the point Will scat smoothly andfirmly against the frog .and have an extended support or bearingthereon. The point is provided with a pluthe openings 16 and alsopermitting a short worn bar to be firm1y secured to thefrog.

.The, .har,15 ,.is twisted slightly toward its opposite ends so that theupper and of the bar, when the same is in position, Will projectforwardly and operate as a shin, as indicated at 20, While theextremities of the bar are turned slightly ontwardly or away from thecenter of curvature of the bar, as shown at 21, so as to provide spnrsor points which will readily penetrate the ground. Shonld one cnttingand or point of the bar bacome Worn or dull throngh long continnad use,the bar may be ramoved and replacad after baing inverted so that theunused and Which wastormerly uppermost will become the working and andWill penetrate the ground; Theperiod during which the plow cannot beused will, therefora, be of 110 consequence inasmnch as the point may bein verted by the user in the field and the securing bolts ara accessibleinasmuch as they are inserted throngh the lateral rib 19 and are therbyspaced .f'rom the side of the frog. As the bar becomes shorter throughprotracted use and traquent sharpening it may be set lower upon theconcave curved front adge of the frog and will scat firmly against thesame, the tnrned point or spnr 21 being received'in sockets orcorrngations 22 in the front side 01: the frog so that the point willseat fir1nly against the'frog and a short bar will etficiently resist.the thrnst npon the pl'ow whan it is in use, Shonld the bar bacoma varyshort, a short piece of metal or an old worn ont point may be securedupon the frog above the point whi'ch is in use so that the front of thefrog may be protected from wear andthe slots l8.cannot clog up.

The construction permits the use of a bar until naarly all of it is wornaway ina smnch as it may be used until the nppar opening 16 in the barWill pass below the lower and ofthe loWer slot 18 in the rib 19, as willbe readily nnderstood.,

The moldboard 23 is secuied; to the front side of the frog and fitsagainst the edge of thepoint 15 so as to be flush thereWith and theshare 24 is secnred to the l.owar and of the frog and connected with thel'ower adge .of the moldboard by suitable bolts and at- 'tzching plates,as Will be readily understo0d.

The share is Symmetrical so that it may be reversed to accommodata forwear and its longitudinal edges are beveled, as shown at 25, so that thelower edge Will readily enter the ground; While the upper edge will, fitover the lower bevelad edge of the 1nololboard and bring the front facesof adjusted end:wise upon the frog and this adjnstment permits me to setthe point so that it Will penetrate the ground to any desired depth. Itis necessary, of course, to adjust the landside and the beam tocorrespond to the adjustment of the point, and the slot I in the upparportion of the frog permits the neaded adjnstment of the beam relativeto the frog. To aid in holding the beam and the frog in their properrelative positions, lugs, corrugations or projections 26' are providedupon theopposed faces of the standard and the frog. A locking kay orwedge 27 is also provided, the front face of the said ke v or wedgabeing preferably straight and beingprovidcd Wi-th transvarse grooves ornotches 28 adapted tobe engaged by the upper rear edge of the moldboardsupporting member of the frog and the rear side of the wedge or keybeing cnrved so that it ma) fit closely against the front cnrved side ofthe standard, as shown clearly in Fig. 4. This locking key or wedge iscarried by the upper and of a bar or link 29 which has its lower andseau-red to the landside 9 nearthe rearand thereof, the upper and ofsaid bar or linkbaing provided with a plurali-ty of openings 30 thronghany one of which an attaching:bolt inay be inserted into the wedge orkey so that the 'working length of thebaror link may be varied to suitthe adjnstmant 'which ma be given the landsida and the wedge. lVhen achange in the relative position of the frog and the standard or beam isnecessary or desired the bolt 6 is loosened and the standard or beamthen moved pivotally npon the boit 8 until it reaches thedesiredposition after Which the Wedge 27 is aclji1stad so that it willfit snugly batween the front portion of the frog and the front side ofthe Ieam or standard. Tha'bolt 6 is then tightaned and the parts will beheld fi'rmlyiir the position in which thay have beau: set..

It Wll'l be readily sean fromthe foregoing description, taken inconnection With the accompanyingj drawings, that I have pro vided a verysimple structure by which the efliciency of a turningplowwill haenhanced. The point, owing to its reversibility and its symmetrical formand the fact that it is formed on a simple, regnlar carra so that ithas. a long baaring-upon the front side of the f'rog, may be used foravery long ti-1ne without reqniring; the provision ofa non point and theslight twist giventhe extremities of' the pointnot onl'y permit it toreadil;y enter the gronnd to the desired deptl1 but. also ai'd inholding it in its proper 7 position, whenit, has hecome worn as theupper and of the point in use Will engage a socket in the front faceofthe frGg and thareby serve as a brace to prevent the point slipping uponthe f-rogwhenthe plow happens to strike a: large rock or otherobstruction. By properly forming the bevels on the longitudinal edges ofthe share and fitting the securing bolts in slots the share may beadjusted forwardly so as to compensate for waar and consequently, may beused for a long time without requiring the provision of a new share.

Having thns dascribed the invention, what is claimed as new is:
